Step-by-step explanation:
To find the area of the shaded region, you must find the area of the larger rectangle [(x+10)×(2x+5)] and subtract the area of the smaller rectangle [(x+1)×(x+1)] from it.
First, you simplify the larger rectangle's area:
(x+10)×(2x+5) =
Then, simplify the smaller rectangle's area:
(x+1)×(x+1) =
Finally, subtract the smaller rectangle's area from the larger rectangle's area:
Therefore, the final answer is .

In order to find the area of the semicircle, or the shaded region, we just have to find the area of the entire circle and divide it by 2. The formula for the area of a circle is 
. With the given diameter of 12, we can deduce that the radius is 6.
Area of Semicircle = (
/2)
Area of Semicircle = (3.14 x 36/2)
Area of Semicircle = (3.14 x 18)
Area of Semicircle = 56.52

Mafalda's save percentage improved by 0.153.
<em><u>Solution:</u></em>
Given that, Mafalda has a save percentage of 0.7380 so far this hockey season
Last season, her save percentage was 0.5850
<em><u>To find: Percentage improved</u></em>
To find improvement in Mafalda's save percentage we will subtract last season's save percentage from this season's save percentage.
From given,
Last season save percentage = 0.5850
This season save percentage = 0.7380
Percentage improved = This season save percentage - Last season save percentage
Thus Mafalda's save percentage improved by 0.153.
